Nice, kicking the queen while creating a fork threat but I do see something black could do to combat it: Qc5

Good insights.
After 5...Qc5, White could play 6.Qf3!
Apparently Qd6 is a better move, here is what stockfish says about the position you provided: 
Black is winning, probably best to just play traditionally against the scan, since white gets around a full point of advantage

-1.e4 d4 2.exd5 Qxd5 3.Nc3 Qa5 4.b4 Qxb4
Then...
5.Nd5!
